Usually within 2–3 days. Corrections to articles are handled first.

🧾Include details

Your Excel/Office version, the exact error message and what you expected to happen.

🔒No confidential data

Please do not send real customer data, salaries or passwords. A small made-up example is perfect.

Before you write

My formula shows #NAME? — is the article wrong?

Usually the function is newer than your Excel (XLOOKUP, FILTER, TEXTJOIN…). Check the version note in the article, or use the INDEX-MATCH alternative shown there.

The macro gives run-time error 1004

Read 7 causes of error 1004 first — it solves most cases. If not, send the line that is highlighted in yellow when you click Debug.

Can you build a custom macro or tool for me?

I cannot take every request, but interesting problems often become free tools or articles for everyone. Describe it with the “Tool idea” card.
